Abstract: An energy storage system configured to reduce damage caused by a flame in response to a battery igniting. The energy storage system includes a cabinet, a battery modules inside the cabinet and each including a vent, a first channel facing the vent and including a first end portion and a second end portion spaced apart from each other in a first direction, a second channel inside the cabinet and connected to the second end portion, a guide member in the first channel and configured to guide movement of a flame or gas discharged from the vent in the first direction, and a discharge member connected to the second channel and configured to discharge a gas introduced into the second channel to the outside of the cabinet.

Abstract: A door for an energy storage system includes: a first door frame; a second door frame facing the first door frame; a door channel between the first door frame and the second door frame; an inlet hole passing through the first door frame and configured to allow a flame or gas to be introduced into the door channel; a discharge hole passing through the second door frame and configured to allow a flame or gas to be discharged from the door channel; and a blocking member facing the discharge hole and configured to block a flame that is discharged from the discharge hole from passing therethrough.

Abstract: An embodiment of the present invention relates to a fire-extinguishing system of an energy storage device including a plurality of battery racks for receiving a plurality of battery modules, the fire-extinguishing system comprising: a sensing part for detecting at least one of a temperature, a voltage, and smoke of a battery module; and a fire-extinguishing part for injecting a fire-extinguishing chemical to the battery module when at least one of values detected by the sensing part exceeds a predetermined threshold value, wherein the fire-extinguishing part further comprises a pipe fitting member provided on a path through which the fire-extinguishing chemical is supplied with respect to the battery rack to change a supply pressure of the fire-extinguishing chemical.

Abstract: A fire extinguishing system for an energy storage device having a battery rack for a battery module, the fire extinguishing system including a sensing unit configured to detect when a value of one or more of a temperature of the battery module, a voltage of the battery module, or smoke from the battery module is higher than a preset threshold value; and a fire extinguishing unit configured to provide a fire extinguishing agent to the battery module when the sensing unit detects that the value is higher than the preset threshold value, the fire extinguishing unit including a heat-sensitive member. The heat-sensitive member is positioned at a battery cell vent hole for a battery cell in the battery module. The heat-sensitive member is configured to allow the fire extinguishing agent into the vent hole by being melted when a temperature of the heat-sensitive member is higher than a predetermined temperature.

Abstract: A power generation system which generates electric power includes a fuel cell system in which supplied reactants react to generate electric power and a circulation system that circulates a product generated by the fuel cell system. The circulation system is configured to resupply at least some elements of the product generated by the fuel cell system as a reactant of the fuel cell system.

Abstract: A movable lift device including a rotatable bed which can be lifted or rotated by a user, with laying a user thereon. The movable lift device having a rotatable bed includes a base frame comprising a plurality of wheels installed therein; a post rotatably coupled to the base frame, the post upwardly extended from the base frame a predetermined length in an “L” shape; and a bed comprising a bed part that is able to ascend along the post, the bed part allowing a user to lie thereon. The post rotatably supporting the bed has an “L” shape and the supporting point of the post rotatably supporting the bed is formed in the center of the base frame, such that the structure may be stably maintained even when the bed having the patient lying thereon is rotated, only to prevent an accident of overturning the movable lift device.

Abstract: There is disclosed a senior-friendly shower carrier comprising a bed; a housing part comprising a second housing, a first housing coupled to a lower portion of the bed to elevate to an upper portion of the second housing and a third housing that elevates to a lower portion of the second housing; a first elevating module comprising a driving motor having a shaft provided therein, a fixing part, a power transmitting part which transmits a rotational force of the shaft to the fixing part, and a moving part which elevates the first housing upwardly, moving along the rotation of the fixing part upwardly and downwardly; and a second elevating module comprising a driving motor having a shaft provided therein, a fixing part, a power transmitting part which transmits a rotational force of the shaft to the fixing part, and a moving part which elevates the third housing downwardly.
